"Woe to me if I preach not the gospel."

I made this chart that gives an overview of the Biblical prophets years ago and have found it to be quite useful over the years. It is designed to help memorize where each prophet fits in historically. Once you break it down this way, it is not as hard to commit them to memory. If anything, it gives you a visual to help sort out the flow of biblical history and the role of each prophet.
